And finally that meant the insights from them don't have to be re-introduced by me over and over, as people saw that these diagrams only illustrate the "brute-force" rules of play, which exist in ways that permit more flexible and elective rules to be applied when they should, and all of which together, creates a play-space among us in which other human dynamics can begin to cause things of their own.
Long ago, I called something the Fruitful Void, and not long after, Vincent followed up with something called the Whirlwind. Come and see what we're talking about.
